Hydrogeology field investigation is the preliminary work for modeling the transmission of contaminant and analyzing the attribution of responsibility Reconstruction of the heterogeneous field can help to clarify the movement of contaminant in groundwater Previous studies indicate that in situ hydrogeology may show highly heterogeneous and the behavior of solute transport is much different from that of homogeneous field Due to hydraulic test and laboratory experiments are expensive and time consuming samples of hydraulic conductivity are sparse to describe the heterogeneous field This study uses lithifacies which is abundant and is indirectly related to the property of hydraulic conductivity Indicator kriging a non-parametric geostastical method is used to interpolate the category data and build heterogeneous field for the solute transport modeling The results indicate that if data is sufficient indicator kriging with stratified sampling data is effectively reconstruct the high heterogeneous distribution of hydraulic conductivity When the variance of hydraulic conductivity is close to 1 the indicator field produced by indicator kriging can well represent the results of flow and solute transport modeling in the true field When variance comes to 5 21 indicator kriging still represent the result of flow modeling and the distribution of spatial variable the result of solute transport modeling in indicator kriging field has some difference from the result in true field
